摘 要：通过对硫化矿浮选体系中黄药的分布状态、测试方法的研究,找到了黄药的解吸、转化以及消除对测试干扰因素的办法.使浮选矿浆中的黄药检出率达到97%左右.指出了硫化钠在黄药测试中的重要作用.
Abstract: Based on the research on the existent forms of xanthate in the sulphide pulps and theanalysis methods, the procedures of desorption and transformation of xanthate and itsderivative from the surface of minerals are found and the ways to eliminate the interferingfactors of analysis are obtained.As a result the detective coefficent of xanthate reaches 97%.It has been indicated that Na2S plays an important role in the analysis.Na2S can completelydesorp xanthate and its derivative from the surface of minerals. Meanwhile Na2S can promotedixanthogen or heavy metal xanthate to transform into xanthic ion and eleminate the interfering action of heavy metal ions in the pulp.
